Abstract (en)
The present invention uses memory resources effectively and connects each storage device by a plurality of paths in a switchable manner, thus improving reliability and ease of use, by virtualizing external memory resources as internal memory resources. External storage 2 is connected to the main storage 1, and the actual volume 2A is mapped onto the virtual volume 1A. A plurality of paths is connected between the storage 1 and 2. When a failure occurs in a path in use (S3), the path having the next highest priority is selected (S4), and processing is continued using this path (S5).
